The DF Remaster has a high-resolution, true colour version of the in-game PDA interface and all its contents, including the mission briefings.
The assets are contained in the game's enhanced directory, and images are in PNG format.
Some items are contained in enhanced\menu and others are contained in enhanced\dfbrief subfolders. This appears to correspond to DFBRIEF.LFD and MENU.LFD
Enhanced DFBRIEF assets
All of these appear to be rely on the original DELT data in DFBRIEF.LFD for correct positioning on the screen. They appear to be exactly double the dimensions (width and height) of the original DELTs.
